I wouldn't risk a generic untried chip that has no reviews on a C63 whatever the cost. If you really want to remap your car, look no further than Eurocharged. Tried , tested and known to work.
I agree, there is no comparison between a remap and a tuning box, had one on my old ml270 and was terrifyingly unpredictable, I definitely would not put one in the same 10mile radius as a c63 if I had one.
Eurocharged look awesome, I swear by the guy I use at black code usually but I'm guna try these guys out I think
Yeah i am looking at Mygenius tool + Maps for the amg. Just came across this and thought if anyone had any info on them. Can't wait to get mine over 500 horses.
